I've had my Lumia 920 connected via USB to sync just fine, but I'd much rather connect it via Bluetooth. So far though, I haven't found an option in the software.
Is this even possible? If so, what's the process?
Lumia 920 runs Windows Phone 8, which currently does not support any wireless syncing.
The closest thing you can get is syncing photos/images to OneDrive. Hopefully this is a feature that will come, together with syncing via WiFi.
